T-Mobile launching nationwide UMA this summer {Engadget Mobile}

May 3rd 2007 10:19PM To further Matt's comments, if someone confirms that TMobile does indeed have seamless handover going from Cellular to Wifi, what sort of handover delay does the user experience? Is it in the order of seconds, tens of seconds?

Also, on these phones, will I be able to use it on ANY Wifi network, or does it have to be a T-Mobile hotspot? I would also like to have the capability of using the Wifi separately while I am home to communicate over Wifi between multiple phones in the same Wifi Zone (at home). Is that possible?
